Abstract/Index

We study immigration policy in a small open receiving economy under self-selection of migrants. We show that the immigration policy choice aspects and is affected by the
migratory decisions of skilled and unskilled foreign workers. From this interaction multiple equilibria may arise, which are driven by the natives' expectations on the size and skill composition of the incoming migrant population (and, hence, on the welfare effects of immigration). In particular, pessimistic (optimistic) beliefs induce a country to impose higher (lower) barriers to immigration, which crowd out (crowd in) skilled migrants
and thus con�rm initial beliefs. This self-ful�lling mechanism sustains the endogenous formation of an anti or pro-immigration "prejudice".
